antithrombin knockdown antibody

An antithrombin knockdown antibody (or anti-antithrombin antibody) is an antibody designed to bind and neutralize or deplete antithrombin (antithrombin III), a key natural anticoagulant that inhibits thrombin and factor Xa. In research settings, such as in vitro thrombin generation assays, polyclonal antibodies (e.g., sheep anti-human antithrombin antibodies) are used to experimentally deplete antithrombin levels to simulate hemostatic rebalancing. Therapeutically, anti-antithrombin antibodies and single-domain antibodies (nanobodies) are being explored as non-factor replacement therapies for hemophilia A, hemophilia B, and other rare coagulation factor deficiencies. By blocking the inhibitory activity of antithrombin, these antibodies promote thrombin generation and restore hemostasis in patients with bleeding diatheses.
